Contrails
April 30th, 2004
This infra-red image from NASA’s Earth Observatory reveals a ghostly web of contrails over the south-eastern United States.
Spectacular as the image is, there’s a downside to such a spectacular image: there’s some evidence that an increase in the quantity of contrails contributes to an increase in the level of cirrus cloud cover, which in turn contributes to an increase in ground and atmospheric temperatures.
